1 Honors Chemistry Extra Stoichiometry Problems 1. Silver nitrate reacts with barium chloride to form silver chloride and barium nitrate. a. Write and balance the chemical equation. 2 AgNO3 + BaCl2 ! 2 AgCl + Ba(NO3)2. b. If grams of barium chloride are reacted in an excess of silver nitrate, how many representative particles (and what type) of silver chloride are produced? ! 1 ! 2 10!" .. = 10!" .. 1 ! 1 ! 1 . c. If grams of barium nitrate are produced how many grams of silver nitrate were reacted? ( ! )! 1 ( ! )! 2 ! ! = ! 1 ( ! )! 1 ( ! )! 1 ! 2. Nitrogen gas is reacted with hydrogen gas to form nitrogen trihydride. a. Write and balance the chemical equation. N2(g) + 3 H2(g) ! 2 NH3(g). b. How many liters of nitrogen trihydride are produced at STP if grams of hydrogen gas are reacted in an excess of nitrogen? ! 1 ! 2 ! ! = ! 1 ! 3 ! 1 ! c. How many grams of hydrogen are needed to fully react grams of nitrogen gas? ! 1 ! 3 ! ! = ! 1 ! 1 ! 1 ! d. How many liters of nitrogen gas are needed to completely react L of hydrogen gas at STP?
2 ! 1 ! 1 ! ! = ! 1 ! 3 ! 1 ! OR. ! 1 ! = ! 1 3 ! 3. For the following problem, use the following chemical equation: C8H18(l) + O2(g) ! CO2(g) + H2O(g). a. Balance the chemical equation. 2 C8H18(l) + 25 O2(g) ! 16 CO2(g) + 18 H2O(g). b. How many moles of oxygen are needed to fully react grams of C8H18? ! !" 1 ! !" 25 ! = ! 1 ! !" 2 ! !". c. How many liters of carbon dioxide gas are formed at STP when x 1025. representative particles of C8H18 are reacted in an excess of oxygen gas? 10!" ! !" 1 ! !" 16 ! ! !". = 10! ! 1 10 ! !" 2 ! !" 1 ! d. How many grams of water are produced when liters of oxygen gas at STP are fully reacted? ! 1 ! 18 ! ! . = ! . 1 ! 25 ! 1 !.
